Seeking Parsley Root

Over the next few weeks, if you see parsley root for sale anywhere in Brooklyn, please let me know. It's an ingredient in my departed grandmother's chicken soup, but it's no longer easily found. Thanks!

Thank you all! I found them at Circus, to which I'd never been - it's a great produce market. I hope to try out the other shops recommended above. In the meantime, it's on to the soup making!Thanks again.jns7
